Abstract

Channel Quality Indicator (CQI) tables are tailored to one or more cells of interest. Tailoring CQI tables to individual cells permits devices such as radio base stations to more reliably and accurately allocate radio resources to those cells since channel conditions vary from cell to cell. According to one embodiment, a table of CQI values is composed by analyzing information indicating channel quality in a cell of interest and generating at least one table of CQI values tailored to the cell of interest based on the information analyzed. The tailored CQI table may be deployed to another device for use in reporting channel quality information. The device may report channel quality by accessing the tailored CQI and identifying the range of CQI values that includes a channel quality estimate derived by the device. The device generates a channel quality information message based on the identified range of CQI values.

Description

生成、布置及使用定制的信道质量指示符表 Generating, using a custom layout and channel quality indicator table

技术领域 FIELD

[0001] 本发明一般而言涉及无线通信,特别涉及定制(tailor)信道质量信息消息。 Generally [0001] The present invention relates to wireless communications, and more particularly to customized (Tailor) channel quality information message.

背景技术 Background technique

[0002] 诸如第三代(3G)系统及以上之类的高级无线通信系统采用了各种技术来提高数据吞吐量和信号传输质量。 [0002] such as third generation (3G) system or the like and more advanced wireless communication systems employ various techniques to improve data throughput and signal transmission quality. 这些技术中的许多是基于对瞬时信道条件的估计,比如路径损失和阴影、干扰变化、以及快速多径衰落。 Many of these techniques are based on estimates of instantaneous channel conditions such as path loss and shadowing, interference variations, and fast multipath fading. 常规上通过诸如蜂窝电话之类的设备来测量瞬时信道质量条件,并且将其宽泛地称作信道质量指示符(CQI)。 Measured by conventional devices such as cellular telephones instantaneous channel quality conditions, and are broadly referred to as Channel Quality Indicator (CQI). CQI值可以对应于信噪比(SNR)、信干噪比(SINR)、接收信号功率或强度级、可支持的数据速率、可支持的调制和/或编码速率、可支持的吞吐量等等。 CQI values ​​may correspond to SNR (the SNR), signal to interference noise ratio (the SINR), received signal power or intensity level, supportable data rates, supportable modulation and / or coding rate, throughput, etc. supportable .

[0003] 常规上例如通过物理层信令把CQI信息从诸如蜂窝电话之类的无线接收机传送到相应的发射机。 [0003] e.g., by the corresponding physical layer signaling information CQI transmitted from the transmitter a wireless receiver such as a cellular phone to conventionally. 在一个例子中,通过服从高速下行链路分组接入(HSDPA)协议的专用反向链路在基于宽带码分多址(WCDMA)的系统中传送CQI信息。 In one example, a dedicated reverse link (HSDPA) protocol transmitting CQI information in a system based on Wideband Code Division Multiple (WCDMA) in the subject by the high speed downlink packet access. 无线传输系统使用CQI信息来帮助无线电资源分配。 Wireless transmission system using the CQI information to help radio resource allocation. 例如,CQI信息可以被用来确定多个接收机之间的传输调度、选择合适的传输方案(例如将要激活的发射天线的数目)、确定带宽分配、选择扩频码、确定调制和编码速率等等。 E.g., CQI information may be used to determine transmission scheduling among multiple receivers, to select suitable transmission schemes (e.g., the number of transmitting antennas to be activated), determines the bandwidth allocation, selecting a spreading code, modulation and coding rate determines the like Wait.

[0004] 常规上按照CQI消息的形式传送CQI信息。 [0004] Conventionally CQI information transmitted in the form of CQI message. 接收机通过首先测量信道质量(例如SNR或SINR)形成CQI消息。 A receiver by first measuring the channel quality (e.g., SNR or SINR) is formed CQI message. 所述接收机随后访问标准化的CQI表,其中该表包含被唯一索引的各CQI值范围。 The receiver then access normalized CQI table, wherein the table comprises a range of values ​​is unique for each CQI index. 通过选择相应的索引值来识别出所测量的信道质量落在其中的该范围。 By selecting the appropriate index value to identify the channel quality measurement falling within the scope therein. 例如利用(20,5)块编码技术把所选择的索引值映射到一个信道质量信息比特序列,其中把5个比特编码成一个20比特代码字以用于错误防止。 For example using (20, 5) block coding technique to map the selected index value to a channel quality information bit sequence, wherein the 5 bits are encoded into a 20 bit code word for error prevented. 随后把所述已编码信道质量信息比特映射到物理信道上,并且将其作为一条消息来传送。 Then the coded bits of the channel quality information mapped to the physical channel, and transmits it as a message.

[0005] 被存储在常规CQI表中的各CQI值范围是固定的,并且在系统布置之前很久就被预先确定。 [0005] Each CQI value range is stored in a conventional CQI table is fixed, and a long time to be predetermined before the system is arranged. 在一个例子中,与3G通用移动通信系统(UMTS)技术兼容的所有传输系统和小区都使用固定的CQI值表,其具有预定的间距而不管单独的小区特性如何。 In one example, the 3G Universal Mobile Telecommunications System (UMTS) technology compatible with the use of all transmission systems and the cells fixed CQI value table, having a single cell irrespective of predetermined characteristics of the pitch. 在另一个例子中,HSDPA也采用固定的CQI表,其中各CQI值范围分隔开IdB功率差而不管单独的小区特性如何。 In another example, HSDPA also uses fixed CQI table, where each CQI value range separated IdB power difference regardless of the individual characteristics of the cell. 这样,常规上使用通用的CQI值表来形成CQI消息,而不管可能出现在无线接入网内的各小区之间的异常或差异如何。 Thus, to form a CQI message using a common conventional CQI value table, and how to abnormal differences between the cells or may occur regardless of the radio access network. 另外,UMTS和HSDPA都采用具有5比特固定长度的CQI消息来表示CQI值的可用范围,而不管单独的小区特性如何。 Further, UMTS and HSDPA CQI messages are used having a fixed length of 5 bits to represent the available range of CQI values, regardless of the individual characteristics of the cell.

具体实施方式 Detailed ways

[0022] 图I示出无线通信网络10的一个实施例。 [0022] FIG I shows a wireless communication network 10 embodiment. 所述网络10为各种地理区域(也被称作小区12)提供无线服务。 The network 10 in various geographical regions (also referred to as a cell 12) providing a wireless service. 为此,无线电基站14为移动设备16提供无线电资源并且保持与移动设备16的无线电链路,所述移动设备16比如是由所述基站14服务的位于所述小区12内的蜂窝电话。 For this purpose, the radio base station 14 to mobile device 16 provides radio resources and maintains radio links with the mobile device 16, such as the mobile device 16 is located in the base station of the serving cell 14 in the cellular telephone 12. 无线电网络控制器18控制所述基站14、管理无线电网络资源、并且提供到所述基站14、其他无线网络(未示出)以及核心网络20的接口,所述核心网络20比如是公共交换电话网和/或因特网。 The radio network controller 18 controls the base station 14, the radio network resource management, and provided to the base station 14, a wireless interface to other networks (not shown) and a core network 20, the core network 20 such as the Public Switched Telephone Network and / or the Internet. 每一个基站14确定如何将其无线电资源分配到其所服务的移动设备16,这部分地是基于从所述移动设备16到对应的基站14的信道质量估计反馈而实现的。 Each base station 14 determines how to allocate its radio resources to the mobile device 16 it is serving, in part, is an estimate of channel quality feedback from the mobile device 16 to the corresponding base station 14 is achieved based.

[0023] 所述移动设备16按照信道质量指示符(CQI)消息的形式传送信道质量估计。 [0023] The mobile device 16 in the form of (CQI) message transmission channel quality estimate according to a channel quality indicator. 移动设备16通过访问与感兴趣小区12相关联的CQI表22并且识别出包括由该移动设备16导出的信道质量估计的CQI值范围而形成CQI消息。 CQI of the mobile device 16 by accessing the cell of interest 12 associated with the table 22 and recognizes that comprises deriving the estimated channel quality of the mobile device 16 to form a range of CQI values ​​CQI message. 与所识别出的该CQI值范围相关联的索引值被映射到相应的一系列比特并且被传送到相应的基站14。 And the identified CQI value of the range index value is associated with a respective series of bits mapped to and transmitted to the respective base station 14. 该基站14接收所述消息、解码所述消息比特、并且部分地基于所接收到的索引值来调节其无线电资源的分配。 The base station 14 receives the message, decodes the message bits, and based in part on the received index value is adjusted to allocate its radio resources.

[0024] 针对特定的感兴趣小区12 (例如其中当前正为特定设备16提供服务的小区12)来定制由所述移动设备16访问的CQI表22。 [0024] 12 (e.g., where the currently serving cell 12 for a particular device 16) for a particular cell of interest customized by the mobile device 16 access the CQI table 22. 由于信道条件会在小区之间发生改变,因此通过使用针对各单独的小区12的信道条件所定制的CQI表22所得到的信道质量反馈机制与使用常规的标准化的表相比要更准确。 Due to changing channel conditions may occur between the cells. Therefore, by using for each individual cell channel condition 12 of the customized CQI table 22 obtained channel quality feedback mechanism using the conventional normalized table to be more accurately compared. 对定制的CQI表22的使用将允许所述基站14更加可靠且准确地分配特定小区12内的无线电资源。 The use of custom CQI table 22 will allow the radio base station resource 14 more reliably and accurately dispense the particular cell 12.

[0025] 为了表明使用定制的CQI表22的益处,图2示出在郊区宏小区环境中报告的常规的基于高速下行链路分组接入(HSDPA)的CQI索引值的示例性分布。 [0025] In order to show the benefits of using a customized CQI table 22, FIG. 2 shows a conventional exemplary distribution based on High Speed ​​Downlink Packet Access (HSDPA) CQI index values ​​reported in the suburbs macro cell environment. 每一个索引值表示一个信干噪比(SINR)范围。 Each index value represents a signal to interference noise ratio (SINR) range. 所报告的索引的分布不是均匀的,从而表明移动设备往往以高于其他CQI索引值的频率报告一些CQI索引值。 Reported index distribution is not uniform, indicating that the mobile device often than the other frequency values ​​reported CQI index CQI index number. 尽管一些常规索引值被报告的频率往往高于其他索引值,但是所述常规的索引值仍然表示具有与报告频率较低的索引值相同的分辨率(IdB的SINR)的CQI值范围。 Although some conventional frequency index value is often higher than the reported values ​​of other index, but the index value of a conventional still represent the same lower reporting frequency index value resolution (IdB of SINR) CQI value range. 因此,在移动设备频繁地报告相同的CQI索引值时,基站变得难以在所述移动设备之间进行区分。 Accordingly, the mobile device reports the same CQI index frequently, the base station becomes difficult to distinguish between the mobile device. 也就是,在所述示例性郊区宏小区环境中被服务的移动设备往往会以更高频率报告CQI索引值的所述相同有限范围,从而使得难以在具有更好的无线电接收与不具有更好的无线电接收的移动设备之间进行区分。 That is, in the exemplary mobile device suburban macro cell environment and services are often limited the scope of the same report CQI index values ​​at higher frequencies, making it difficult having better radio reception and having no more to distinguish between the mobile device radio reception. 如果最有可能由移动设备报告的信道质量估计是不可区分的,则可靠且准确的无线电资源分配就变得困难。 If the most likely estimate channel quality of the mobile device reports are indistinguishable, the reliable and accurate radio resource allocation becomes difficult.

[0026] 图3示出常规的基于HSDPA的CQI索引值的另一种示例性分布,其中所述索引值表示在城区微小区环境中报告的信道质量估计。 [0026] FIG. 3 shows another conventional exemplary HSDPA distributed based on the CQI value of the index, wherein the index value is represented in the micro cell environment reported channel quality estimate town. 所报告的CQI索引值的分布也是不均匀的,但是并不类似于与先前描述的所述郊区宏小区环境相关联的分布。 Distribution of the CQI index reported is not uniform, but the distribution is not similar to the macro-cell environment associated suburban previously described. 这两种分布之间的差异表明,信道质量在小区之间会发生改变。 The difference between these two distributions indicates that the channel quality will change between cells. 例如,所述城区微小区环境一般来说具有更好的信道质量,正如更高CQI索引值的偏斜分布所指示的那样(其中更高的索引值表示更好的测量信道质量)。 For example, the urban environment in general micro cell with better channel quality, higher CQI index as skew distribution as indicated by the value (where a higher index value indicates a better channel quality measurement). 可以通过针对某一感兴趣小区12定制一个或多个所述CQI表22来改进该感兴趣小区12内的无线电资源分配。 Table 22 can be improved radio resource allocation within the cell 12 of interest by tailoring one or more of the CQI for a certain cell 12 of interest.

[0027] 可以基于指示一个或多个感兴趣小区12中的信道质量的信息来针对所述小区12定制所述CQI表22。 [0027] may be based on channel quality information indicative of one or a plurality of channels of interest in the cells 12 to the cell 12 for customizing the CQI table 22. 如图4的步骤100所示,分析与每一个感兴趣小区12相关联的信道质量信息。 Analysis channel quality information associated with each of 12 cells of interest in step 100 of FIG. 4 FIG. 如图4的步骤102所示,随后使用所分析的信息来生成针对所述感兴趣小区12所定制的CQI表22。 Step 102 shown in FIG. 4, and then generates a CQI for the cell of interest customized 12 Table 22 using the analyzed information. 可以例如在所述网络10的设计或布置期间一次性定制所述CQI表22,也可以周期性地定制所述CQI表22以便反映不断改变的信道条件。 Or can be arranged, for example, during the design of the network 10 of the disposable customized CQI table 22, may be periodically customizing the CQI table 22 to reflect changing channel conditions.

[0028] 在一个实施例中,被用来定制所述CQI表22的信息对应于由感兴趣小区12内的移动设备16所报告的CQI消息。 [0028] In one embodiment, the information used to customize the CQI table 22 corresponding to the 16 cell reported by the mobile device of interest within the CQI 12 message. 根据该实施例,分析在所述感兴趣小区12中报告的CQI消息,并且把各CQI值范围选择成使得以近似相等的概率报告每一个值范围。 According to this embodiment, the cell of interest in the analysis report the CQI 12 message, and the CQI value for each selected range so that approximately equal to the probability of a range of values ​​for each report. 这样,把预期最为频繁地报告的信道质量估计分组成具有较高精度的范围,同时把预期报告频率较低的信道质量估计分组成具有较低精度的范围。 Thus, the expected most frequently reported channel quality estimation range grouped with high precision, while the low frequency of expected reports channel quality estimation range grouped with lower accuracy. 相应地,因为由所述移动设备16最常测量的信道质量估计是使用更精确的CQI信息报告的,因此无线电资源的分配变得更加准确及可靠。 Accordingly, since the channel quality by the mobile device 16 is estimated to be the most commonly used measure more accurate CQI information reports, allocation of radio resources therefore become more accurate and reliable.

[0029] 图5示出把CQI值范围选择成使得以近似相等的概率报告每一个值范围的一个实施例。 [0029] FIG. 5 shows the range of the CQI value selected such that approximately equal to the probability of a range of values ​​reported for each embodiment of Fig. 图5描绘了对应于先前讨论的郊区宏小区环境的信道质量信息的SINR的累积概率分布函数(CDF)。 5 depicts the channel quality information corresponding to the macro-cell environment suburban previously discussed SINR cumulative probability distribution function (CDF). 所述CDF被划分成各相等段,其中每一个段表示预期以近似相等的概率报告的一个SINR范围。 The CDF is divided into equal sections each, wherein each segment represents an expected range of approximately equal probability of a SINR reported. 例如,在图5中,所述CDF被划分成16个相等段。 For example, in FIG. 5, the CDF is divided into 16 equal segments. 然而,也可以把所述CDF划分成所期望的任何数目的段。 However, the CDF is also possible to divide into any desired number of segments. 为每一个等概率CQI值范围指定一个唯一的索引值,所述索引值形成CQI消息的基础。 Specify a probability for each CQI value range like a unique index value, the index value form the basis of the CQI message. 类似地,图6示出对应于城区微小区环境的信道质量信息的SINR的CDF。 Similarly, Figure 6 shows the corresponding microcell environment of urban SINR channel quality information CDF.

[0030] 在下面的表I中可以看出,对应于所述微小区和宏小区环境的所述定制的CQI值范围都具有变化的精度。 [0030] As can be seen in the following Table I, corresponding to the micro cell and macro-cell environment of the customized CQI value ranges have varying accuracy. 然而与常规的CQI表不同,所述CQI值范围分别具有近似相等的出现概率。 However, different from the conventional CQI table, CQI values ​​of the ranges of approximately equal probability. 因此,当把相应的表22布置在小区12中时,可以预期以相同的出现概率报告每一个CQI索引值。 Thus, when the corresponding table 22 disposed in the cell 12, it is contemplated that the same probability of occurrence for each report CQI index value. 另外,所述CQI值范围是基于指示每一个对应的小区中的信道质量的信息(主要是先前报告的CQI消息)而选择的。 Further, the CQI value range is based on the information indicative of the channel quality corresponding to each letter of the cell (mainly the previously reported CQI message) is selected. 此外,由于所述CDF被划分成16个相等段,因此只需要4个比特来把所述索引值映射到各CQI消息比特。 Further, since the CDF is divided into 16 equal segments, so only the 4 bits are mapped to the index value of each bit CQI message. 这表示把常规CQI索引值转换到CQI消息所需的比特数减少了20%,从而降低了CQI消息传输错误的可能性。 This means converting to a conventional CQI index CQI message the number of bits required to reduce by 20%, thereby reducing the likelihood of transmission errors CQI message. 注意,虽然与常规的CQI技术相比少用了一个比特,但是对于预期最常报告的信道质量估计来说,所述定制的表22产生更精确的CQI值范围。 Note that, although compared with conventional technology CQI uses one less bit, but the channel quality estimation is expected most frequently reported, the customized table 22 generates more accurate CQI values.

[0032] 在另一个实施例中,通过把CQI值范围选择成使得以近似相等的代价而不是相等的概率来报告所述范围。 [0032] In another embodiment, the CQI value by the range selected such that approximately equal probabilities are not equal to the expense of the reporting range. 也就是,所述CQI定制过程考虑到与不准确地表示CQI值相关联的代价,比如由于不准确的CQI消息所造成的重传而导致的数据速率降低和/或附加的延迟。 That is, the CQI customization process without taking into account the data rate accurately represents the cost associated with the CQI value, for example due to inaccurate CQI retransmission message caused over the reduction and / or additional delay. 因此,可以通过对CQI值范围进行适当地加权及调节来定制所述CQI表22,从而使得以近似相等的代价来报告每一个范围。 Accordingly, the CQI can be weighted by value range and is appropriately adjusted to customize the CQI table 22, so that approximately equal to the cost of each reporting range.

[0033] 在又一个实施例中,基于指示感兴趣小区12中的信道质量的其他信息来定制所述CQI表22。 [0033] In yet another embodiment, the cell of interest based on the additional information indicating the channel quality in the 12 to 22 customizing the CQI table. 例如,可以使用以下信息来定制所述CQI表22 :小区尺寸、由所述网络10所支持的射频重用模式、小区地形特征、在所述小区12内所支持的发射和接收天线配置、所估计的或实际的信号传输负载条件、或者可以直接或间接地指示所述小区12内的信道质量的任何其他信息。 For example, the following information may be used to customize the CQI table 22: cell size, supported by the radio network 10 reuse pattern, cell terrain features within the cell 12 supported by the transmitting and receiving antenna configuration, the estimated or actual signal transmission load conditions, or may be directly or indirectly, any other information indicating the channel quality in the cell 12. 不管所分析的信息类型如何,通过基于与一个或多个感兴趣小区12相关联的信道质量信息定制所述CQI表22来得到一种更准确的信道质量反馈机制。 Regardless of the type of information analysis, more accurate channel quality feedback mechanism to obtain a customized based on the channel quality information with a more or cell of interest 12 associated CQI table 22.
